Even though fossils of life that existed 3-3.5 billion years

Biology

pogonyaev3 years ago

Answer:

Fossils are the remains of ancient plants and animals that were buried millions of years back. These are found to be embedded in the sedimentary types of rocks. The earliest known direct fossils are not obtained in the present day, but the imprints of these fossils are explored in many of the places. These were the ancient micro-fossils such as bacterias, cyanobacteria that existed about 3.5 billion years back.

Some of the direct evidence of fossils are obtained from the rocks in the western part of Australia and the southwestern part of Greenland.

Thus, the imprints of these fossils are found in many rocks at different places, and this suggests the existence of life during that particular time frame.

Effector molecule binding changes the behavior of enzymes by altering the equilibrium between the tense (T) state and the relaxe
9966 [12]

Answer:

Explanation:

<h2>Homotropic effector-</h2>
  • \text{accounts for the sigmoidal nature of a velocity versus substrate concentration curve}
  • \text{An enzyme's substrate.}
<h2>Both -</h2>
  • \text{Works by altering T/R ratio.}

The phrase  \text{"accounts for the sigmoidal nature of a velocity versus }

is relevant and can be applied for homotropic effector molecules since the heterotropic effector molecules have the possibility and affinity to change the sigmoidal curve to a more potential hyperbolic curve contingent upon the allosteric effector to be positive or negative modulator.

The expression isn't relevant for both homotropic and heterotrophic effectors since the two of them can tie to the allosteric site of allosteric enzymatic compounds.

The phrase \text{"works by altering the T/R ratio"} is significant and can be applied for both homotropic and heterotropic effectors.

The expression \text{"an enzyme's substrate"} is significant and applied for homotropic effectors just as when substrate molecules tie to the allosteric site of enzyme then it is regarded as homotropic effectors. The heterotropic effectors are effectors apart from substrate molecules.

The phrase \text{"alters the} \  K_m \ \text{ of an enzyme"} is not applied and insignificant to none of the heterotropic or homotropic effector molecules since K_m is significant for the enzymes that obey the Michaelis-Menten equation, but allosteric enzymes do not obey the Michaelis-Menten equation. Homotropic and heterotropic effectors are viable and efficient for allosteric enzymatic chemicals that don't contain

Precipitation in a deciduous forest can be in the form of rain or snow. Please select the best answer from the choices provided
allochka39001 [22]

I believe this is T. Because i just learned that in science not that long ago, and deciduous forests have small winters and long growing seasons, and the small winters have lots of snow, and the long growing seasons have lots of rain.
